ABSTRACT: This invention is concerned essentially with a flexible adhesive tape for hairdressing purposes, including punctured portions, for ventilated attachment to and easy removal from a users person. The instant invention also embraces an apparatus for tape manufacture wherein complementary rolls define a nip through which tape is passed and simultaneously pierced by coaction between projections on one roll and recesses on the other.

HAIRDRESSING TAPE SUMMARY It is an important object of the present invention to provide a hairdressing tape which is more easily applied to a persons hair, affording ventilation thereto for quick drying of the hair, and readily removable from the hair without discomfort.

It is another object of the present invention to provide a hairdressing tape of the type described which is conveniently severable at any' selected location for utilization of a desired tape length.

It is a further object of the present invention to provide unique apparatus for producing tape having the advantageous characteristics mentioned in the preceding paragraphs, which apparatus is extremely simple in construction, maintenance and operation, durable and reliable throughout a long useful life, and produces hairdressing tape at a rapid rate to effect substantial economies in cost.

Other objects of the'present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure. I

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scopewill be indicated by the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIGS. 1 and 2, a tape-manufacturing apparatus is there generally designated 10, and includes supply means 11, such as a journal or shaft 12 rotatably supporting a coil 13 of tape 14.

The tape 14 is advantageously of a flexible sheet material, such as a nonwoven plastic, polyvinyl chloride having been found satisfactory. One side or face of the tape 14, as at 15 is coated with a pressure-sensitive adhesive, of suitable type. The tape 14 upon removal from the coil 13 is trained between a pair of tensioning or idler rolls l6 and 17, and passes thence over an idler roll 18 in the direction of arrow 19.

Downstream of idler roll 18 are a laterally arranged series of complementary pairs of operating rolls 20 and 21. The rolls 20 and 21 of each complementary pair are in generally tangential relation with respect to each other and are respectively rotatably supported by shafts 22 and 23 to define therebetween an operating nip or bite 24.

Each lower operating roll 21, in the illustrated embodiment, may be a piercing roll of generally cylindrical configuration, and having on its periphery a plurality of annular rows or arrays of radially outwardly extending, pointed projections 25. As best seen in FIG. 3, the annular arrays of pointed projections 25 are four in number, but may be greater or less, as desired. Further, the individual projections 25 of the several different annular arrays of projections are arranged in side-byside relation to define transverse rows of projections extending across the peripheral face of the piercing roll 21, and

spaced between opposite sides or end faces of each piercing roll. In addition, the pointed projections 25 may each be of an outwardly tapering pyramidal or obelisk configuration having generally flat, triangular sides or faces intersecting in sharp convergent corners, for a purpose appearing presently.

Each operating roll 20 may be disposed in generally tangential relation with respect to its associated piercing roll 21 and define a backing roll affording support to the tape 14 upon passage through the nip 24 while being pierced by the projections 25. More specifically, each backing roll 20 may be formed in its peripheral surface with a plurality of recesses 26, say in the form of annular grooves of generally rectangular cross-sectional configuration, each sized and arranged to spacedly receive a respective annular array of pointed projections 25, as best seen in FIGS. 3 and 4. Thus, each backing roll 20, by its peripheral surface portions or lands 27 intermediate the grooves 26, effectively maintains the tape 14 in tangential engagement with the peripheral surface 28 of piercing roll 21 while the projections 25 pierce the tape and enter in spaced relation into the grooves 26.

The piercing action of the projections 25 through the tape 14 is best seen in FIGS. 4 and 5, the projections depressing the tape on its adhesive-coated surface 15 to form longitudinal rows of punctured tape portions 30 projecting from the nonadhesive-coated tape surface. The punctured tape portions 30 are also arranged in transverse rows extending laterally across the tape, being spaced between the longitudinal side edges 31 and 32 of the tape. In conformance with the generally pyramidal configuration of each projection 25, the punctured portions 30 are also of generally pyramidal configuration, each having its apex region ruptured or pierced, as at 33, with therupture or opening thereof extending partially along adjacent regions of the corners or edges 34 of the pyramidal-configured punctured portions. Thus, the apex region 35 of each punctured portion 30 is freely flexible in the manner of a small flap.

In addition to the piercing projections 25 and complementary recesses 26, the operating rolls 21 and 20 are formed on their peripheral faces, adjacent to one side or end, with complementary knurling formations, as at 36 and 37. The knurling formations may comprise an annular row of recesses 36 in the piercing roll 21, and a mating annular row of protuberances 37 in the backing roll 20. The formations 36 and 37 combine to define a longitudinal row of knurled formations or depressions 38 extending along one side edge of the tape 14, as along edge 32, see FIG. 5. If desired, a second annular row of recesses may be formed along the other side edge 31 of tape 14, by providing additional knurling formations in a corresponding position on rolls 20 and 21.

From the nip 24, the pierced tape passes over an idler roll 40, as at 41, thence between a pair of rolls 42 and 43 and to a slitting station 44. At the slitting station 44 the tape 41 may be slit into any desired number of narrower tapes, as at 45 and 46 for coiling at 47 and 48 by respective tape-withdrawal means 49 and 50.

The individual coils 47 and 48 may then be employed in hairdressing, as in the setting or holding of a coiffure during drying. It has been found that the particular pierced configuration of tape 14 is admirably well suited for ease of application to a coiffure, the punctured portions 30 affording a high degree of ventilation for rapid drying of the coiffure, as well as case of removal of the tape. The transverse-row arrangement of punctured regions 30 affords weakened laterally extending tape regions for ready severance thereof at any selected location, and the knurling 38 adjacent to an edge 32 facilitates the initiation of manual severance along a transverse row of punctured portions.

In the embodiment shown in FIG. 6, there is illustrated a rotary piercing roll 21a, which may be essentially similar to the piercing roll 21, including a plurality of annular arrays of pointed projections 25a, with the individual projections also arranged in rows extending laterally across the peripheral face of the roll. The backing roll 21b of FIG. 6 assumes the general configuration of a spur gear, having a plurality of radially outstanding, circumferentially spaced teeth 27b, the spaces therebetween defining transversely extending recesses or grooves 26b. In the embodiment of FIG. 6, the grooves or recesses 26b each serve to spacedly receive a respective transverse row of projections 25a for retaining or backing a tape passing between the rolls 21a and 21b during puncture or piercing of the tape.

From the foregoing, it is seen that the present invention provides a unique and highly improved hairdressing tape, as well as apparatus for manufacture of the tape, which fully accomplish their intended objects and are well adapted to meet practical conditions of use.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention and scope of the appended claims.
